This design features a response-biased sampling scheme since individuals living a long time with the disease are preferentially sampled, so naive analysis of the time from disease onset to death will over-estimate survival probabilities. Unconditional and conditional analyses of the resulting data can yield consistent estimates of the survival distribution subject to the validity of their respective model assumptions. The time of disease onset is retrospectively reported by sampled individuals, however, this is often associated with measurement error. In this article we present a framework for studying the effect of measurement error in disease onset times in prevalent cohort studies, report on empirical studies of the effect in each framework of analysis, and describe likelihood-based methods to address such a measurement error.展开更多

Knowledge of prevalent leptospira in a particular animal of a particular geographical area is essential to understand the epizootiology of disease, to understand the linkage between circulating serovars in animals and in humans, and to apply appropriate control measures, etc. Material and Methods: Animal samples from different districts of the south Gujarat region received in the Microbiology department during the year of 2020 for the Microscopic agglutination test (MAT) of leptospirosis were included in the study. Results of MAT which was already performed using 12 different serovars were analysed to prevent serovars in a particular animal. Quantitative data were analysed using frequency and percentage. Result: Out of 1406 animal samples, 151 (11 percent) were positive from animals like cows, buffalos, bullocks and goats. More prevalent serovars in cows were L. ictrohemorrahiae (22%), L. hardjo (19%), L. patoc (17%) and L. pyrogen (16%). In buffalo, L. patoc (58%) and L. hardjo (27%) were found. L. hardjo (50%) in bullock and L. automonalis (50%), L. australis (22%) and L. patoc (14%) in goat were found as prevent serovars. Conclusion: Different prevent serovars has been observed in different animals from the different district south Gujarat region which will be helpful to trace the source of infection in human, to apply control measures, to know the epizootiology of disease, for developing strategies in the future during vaccine development with emphasizing more on the prevalent serovars.展开更多

This paper efficiently mines the top-k probabilistic prevalent co-locations over spatially uncertain data sets and makes the following contributions： 1） the concept of the top-k prob- abilistic prevalent co-locations based on a possible world model is defined; 2） a framework for discovering the top- k probabilistic prevalent co-locations is set up; 3） a matrix method is proposed to improve the computation of the preva- lence probability of a top-k candidate, and two pruning rules of the matrix block are given to accelerate the search for ex- act solutions; 4） a polynomial matrix is developed to further speed up the top-k candidate refinement process; 5） an ap- proximate algorithm with compensation factor is introduced so that relatively large quantity of data can be processed quickly. The efficiency of our proposed algorithms as well as the accuracy of the approximation algorithms is evaluated with an extensive set of experiments using both synthetic and real uncertain data sets.展开更多

The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore,early orthodontic treatment for Class Ⅲ malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class Ⅲ malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class Ⅲ malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class Ⅲ malocclusion through early orthodontic treatment.展开更多

It is associated with both maternal and perinatal morbidity and mortality. The general objective of our study is to determine the prevalence and profile of pregnant women, and to assess the maternal and perinatal prognosis of adolescent childbirth in Kisangani. Methods: This was a prospective, multicenter, case-control observational study conducted over a seven-month period, from February 1 to August 31, 2024, in primiparous adolescent gestational carriers (cases) and primiparous gestational carriers aged 20 to 34 years (controls) who delivered in five health facilities in the city of Kisangani, Democratic Republic of Congo. Results: The prevalence of teenage childbirth was 13.8%. Adolescents were more likely than controls to be in secondary education and to be unemployed. Compared with controls, pregnant adolescents were more likely to have poor ANC attendance. There was a statistical difference between the two groups in relation to pelvic anomaly, rupture of membranes on admission, hypertensive disorders, vicious presentation, caesarean section, episiotomy, postpartum anaemia and puerperal psychosis. In fact, these morbidities were more common in adolescent girls than in controls. Compared with controls, neonatal depression, prematurity, low birth weight and perinatal death were more prevalent in the newborns of teenage mothers. Conclusion: The prevalence of teenage childbirth is high in Kisangani;there is an association between unmarried status, lack of employment, low socio-economic status, poor ANC follow-up and teenage childbirth in Kisangani. The latter is also associated with high maternal and perinatal morbidity and mortality.展开更多

D...Bile reflux gastritis (BRG) is a gastro-intestinal condition especially characterized by the reflux of bile into the stomach, further leading to mucosal inflammation along with various other clinical manifestations. Despite its increasing recognition, BRG remains understudied, with limited understanding of its epidemiology, pathophysiology, and optimal therapeutic strategies. Present narrative review aimed to comprehensively examine the available literature on BRG, focusing on its prevalence, risk factors, pathophysiology, clinical presentation, diagnostic modalities, and available therapeutic strategies. A comprehensive literature search was conducted using PubMed, Embase, Google Scholar and Cochrane databases. Relevant studies were included based on predefined inclusion and exclusion criteria. A narrative synthesis was conducted to summarize and interpret the findings. The prevalence of BRG remains uncertain due to diagnostic challenges. Risk factors include impaired gastrointestinal motility, sphincteric dysfunction (pyloric sphincter and the lower oesophageal sphincter), biliary tract disease, and certain medications. The pathophysiology involves bile acid-induced mucosal injury, inflammation, and impaired gastric defence mechanisms. Clinical manifestations are often nonspecific. Diagnostic modalities primarily include endoscopy and bile acid reflux testing. Management strategies encompass lifestyle modifications, medical therapy, and in severe cases, surgery. BRG is a complex condition with significant clinical implications. Further research is needed to refine diagnostic criteria, elucidate pathophysiological mechanisms, and develop effective therapeutic interventions. Addressing knowledge gaps in epidemiology, risk factors, and long-term outcomes is crucial for improving patient care.展开更多

文摘Prevalent cohort studies involve screening a sample of individuals from a population for disease, recruiting affected individuals, and prospectively following the cohort of individuals to record the occurrence of disease-related complications or death. This design features a response-biased sampling scheme since individuals living a long time with the disease are preferentially sampled, so naive analysis of the time from disease onset to death will over-estimate survival probabilities. Unconditional and conditional analyses of the resulting data can yield consistent estimates of the survival distribution subject to the validity of their respective model assumptions. The time of disease onset is retrospectively reported by sampled individuals, however, this is often associated with measurement error. In this article we present a framework for studying the effect of measurement error in disease onset times in prevalent cohort studies, report on empirical studies of the effect in each framework of analysis, and describe likelihood-based methods to address such a measurement error.
文摘Aim of Study: Leptospirosis is a bacterial zoonotic disease transmitted through contact with animals that are harbouring leptospira. Knowledge of prevalent leptospira in a particular animal of a particular geographical area is essential to understand the epizootiology of disease, to understand the linkage between circulating serovars in animals and in humans, and to apply appropriate control measures, etc. Material and Methods: Animal samples from different districts of the south Gujarat region received in the Microbiology department during the year of 2020 for the Microscopic agglutination test (MAT) of leptospirosis were included in the study. Results of MAT which was already performed using 12 different serovars were analysed to prevent serovars in a particular animal. Quantitative data were analysed using frequency and percentage. Result: Out of 1406 animal samples, 151 (11 percent) were positive from animals like cows, buffalos, bullocks and goats. More prevalent serovars in cows were L. ictrohemorrahiae (22%), L. hardjo (19%), L. patoc (17%) and L. pyrogen (16%). In buffalo, L. patoc (58%) and L. hardjo (27%) were found. L. hardjo (50%) in bullock and L. automonalis (50%), L. australis (22%) and L. patoc (14%) in goat were found as prevent serovars. Conclusion: Different prevent serovars has been observed in different animals from the different district south Gujarat region which will be helpful to trace the source of infection in human, to apply control measures, to know the epizootiology of disease, for developing strategies in the future during vaccine development with emphasizing more on the prevalent serovars.
文摘Background:The human papillomavirus virus(HPV)is very common with over 150 strains and at least 42 acquired by sexual contact.It is a public health concern among women the world over,with an estimated prevalence of 11.7%globally,and 24%in Sub-Saharan Africa.There are five common HPV types;HPV16,HPV18,HPV52,HPV31,and HPV58.Cervical cancer affects women globally,with estimated 570,000 new cases in 2018.Nearly 90%of the 311,000 deaths worldwide in that year occurred in low-and middle-income countries.Objective:To estimate the prevalence of HPV among sexually active women in Lagos,Nigeria;and to determine the most common HPV type among that category.Methods:A descriptive cross-sectional study design was implemented,with 198 women in total enrolled for the study.Sexually active women from various health facilities in Lagos were screened by obtaining cervical tissue,stirred into PCR cell media,and assayed for HPV genotypes using the Roche COBAS®4800 System.Results:Age of the women ranged from 18 to 65 years(mean 34.6±6.4),with the majority(56.4%)between 25-34 years;65%were married and 63%had a secondary education.Age at first penile-vaginal contact ranged from 9 to 38 years(mean 20.4±3.9).Sixty-five percent of women stated total lifetime sexual partners of between 2 and 4(mean 2.9±2.5).The prevalence of high-risk HPV was 40.4%(95%CI:40.1 to 40.7)and breakdown of types obtained were;HPV16,2.5%(95%CI:2.22 to 2.78);HPV18,3.5%(95%CI:3.22 to 3.78);other high risk(OHR)HPV,28.3%(95%CI:28 to 28.6);HPV16&OHR HPV,1.5%(95%CI:1.22 to 1.78);HPV18&OHR HPV,4.1%(95%CI:3.82 to 4.38);HPV16,18&OHR HPV,0.5%(95%CI:0.221 to 0.779).HPV negative and inconclusive results were 58.1%and 1.5%respectively.Conclusion:Prevalence of OHR HPV is high among Nigerian women.This informs the pattern of HPV existing in the African region,and may aid future efforts at eradicating the virus.The findings are further contributive evidence to the initiative to eliminate cervical cancer as a public health challenge in Nigeria.
文摘A co-location pattern is a set of spatial features whose instances frequently appear in a spatial neighborhood. This paper efficiently mines the top-k probabilistic prevalent co-locations over spatially uncertain data sets and makes the following contributions： 1） the concept of the top-k prob- abilistic prevalent co-locations based on a possible world model is defined; 2） a framework for discovering the top- k probabilistic prevalent co-locations is set up; 3） a matrix method is proposed to improve the computation of the preva- lence probability of a top-k candidate, and two pruning rules of the matrix block are given to accelerate the search for ex- act solutions; 4） a polynomial matrix is developed to further speed up the top-k candidate refinement process; 5） an ap- proximate algorithm with compensation factor is introduced so that relatively large quantity of data can be processed quickly. The efficiency of our proposed algorithms as well as the accuracy of the approximation algorithms is evaluated with an extensive set of experiments using both synthetic and real uncertain data sets.
文摘BACKGROUND The prevalence of negative emotional states,such as anxiety and depression,has increased annually.Although personal habits are known to influence emotional regulation,the precise mechanisms underlying this relationship remain unclear.AIM To investigate emotion regulation habits impact on students negative emotions during lockdown,using the coronavirus disease 2019 pandemic as a case example.METHODS During the coronavirus disease 2019 lockdown,an online cross-sectional survey was conducted at a Chinese university.Emotional states were assessed using the Depression,Anxiety,and Stress Scale-21(DASS-21),while demographic data and emotion regulation habits were collected concurrently.Data analysis was performed using SPSS version 27.0 and includedχ^(2)-tests for intergroup comparisons,Spearman’s rank-order correlation coefficient analysis to examine associations,and stepwise linear regression modeling to explore the relationships between emotion regulation habits and emotional states.Statistical significance was set atα=0.05.RESULTS Among the 494 valid questionnaires analyzed,the prevalence rates of negative emotional states were as follows:Depression(65.0%),anxiety(69.4%),and stress(50.8%).DASS-21 scores(mean±SD)demonstrated significant symptomatology:Total(48.77±34.88),depression(16.21±12.18),anxiety(14.90±11.91),and stress(17.64±12.07).Significant positive intercorrelations were observed among all DASS-21 subscales(P<0.01).Regression analysis identified key predictors of negative emotions(P<0.05):Risk factors included late-night frequency and academic pressure,while protective factors were the frequency of parental contact and the number of same-gender friends.Additionally,compensatory spending and binge eating positively predicted all negative emotion scores(β>0,P<0.01),whereas appropriate recreational activities negatively predicted these scores(β<0,P<0.01).CONCLUSION High negative emotion prevalence occurred among confined students.Recreational activities were protective,while compensatory spending and binge eating were risk factors,necessitating guided emotion regulation.

文摘Background:China accounts for one-quarter of the world’s diabetes population,with significant subnational disparities.However,none of the available data have provided comprehensive estimates and projections at both regional and national levels in diabetes prevention and management.This study aimed to explore the temporal trends and geographical variations in the prevalence and non-fatal burden of diabetes by age and sex across China from 2005 to 2023,and to forecast diabetes prevalence through 2050.Methods:We conducted a population-based study based on the nationally representative surveys,and literature reviews.Using the DisMod-MR model and Chinese-specific disease disability weights,we estimated the non-fatal burdens of diabetes,including prevalence and years lived with disability(YLDs),across sexes,age groups,and locations.The temporal trend change was measured as the average annual percent change.The effect of the human development index on burdens was assessed by applying Spearman’s rank correlation analysis.We further projected diabetes prevalence to 2050 under 2 scenarios,the natural trend and the effective intervention on body mass index(BMI).Results:In 2023,an estimated 233 million individuals in China were living with diabetes.Compared to 2005,the agestandardized rate(ASR)of prevalence has increased by nearly 50%,from 7.53%(95%CI 7.00-8.10)to 13.7%(95%CI 12.6-14.8)in 2023.The ASR of YLDs was estimated at 19.1 per 1000 population(95%CI 18.6-19.5)in 2023,compared to 10.5 per 1000 population in 2005.The ASR of prevalence and YLDs was consistently higher in males than in females.The provinces with the highest diabetes prevalence and disease burden were Beijing,Tianjin,and Shanghai.Our forecast results suggest that if existing trends continue,the prevalence of obesity will reach 29.1%(95%CI 22.2-38.2)nationally by 2050,with some provinces in the northern region observing a prevalence of over 40%.Conversely,if effective obesity interventions were implemented,the growth in diabetes prevalence could potentially be suppressed by nearly 50%.Conclusions:The health burden and economic cost associated with diabetes are profound.There is an urgent need to scale up preventive efforts and improve population awareness to enhance disease management and achieve optimal treatment outcomes.

文摘Background:The prevalence,age of onset,and symptomatology of traumatic brain injury,stroke,and neurodegenerative diseases(such as Alzheimer’s disease(AD),Parkinson’s disease,amyotrophic lateral sclerosis,and Huntington’s disease)differ substantially between males and females.The higher prevalence of these brain disorders has been attributed to females having a greater longevity compared with males.Since one of the greatest risk factors of acquired brain injury(such as stroke,traumatic brain injury caused by fall)and neurodegenerative disease is age.
文摘The prevalence of Class Ⅲ malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore,early orthodontic treatment for Class Ⅲ malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class Ⅲ malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class Ⅲ malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class Ⅲ malocclusion through early orthodontic treatment.
文摘Introduction: Adolescent childbirth is a public health and social problem worldwide. It is associated with both maternal and perinatal morbidity and mortality. The general objective of our study is to determine the prevalence and profile of pregnant women, and to assess the maternal and perinatal prognosis of adolescent childbirth in Kisangani. Methods: This was a prospective, multicenter, case-control observational study conducted over a seven-month period, from February 1 to August 31, 2024, in primiparous adolescent gestational carriers (cases) and primiparous gestational carriers aged 20 to 34 years (controls) who delivered in five health facilities in the city of Kisangani, Democratic Republic of Congo. Results: The prevalence of teenage childbirth was 13.8%. Adolescents were more likely than controls to be in secondary education and to be unemployed. Compared with controls, pregnant adolescents were more likely to have poor ANC attendance. There was a statistical difference between the two groups in relation to pelvic anomaly, rupture of membranes on admission, hypertensive disorders, vicious presentation, caesarean section, episiotomy, postpartum anaemia and puerperal psychosis. In fact, these morbidities were more common in adolescent girls than in controls. Compared with controls, neonatal depression, prematurity, low birth weight and perinatal death were more prevalent in the newborns of teenage mothers. Conclusion: The prevalence of teenage childbirth is high in Kisangani;there is an association between unmarried status, lack of employment, low socio-economic status, poor ANC follow-up and teenage childbirth in Kisangani. The latter is also associated with high maternal and perinatal morbidity and mortality.
文摘Bile reflux gastritis (BRG) is a gastro-intestinal condition especially characterized by the reflux of bile into the stomach, further leading to mucosal inflammation along with various other clinical manifestations. Despite its increasing recognition, BRG remains understudied, with limited understanding of its epidemiology, pathophysiology, and optimal therapeutic strategies. Present narrative review aimed to comprehensively examine the available literature on BRG, focusing on its prevalence, risk factors, pathophysiology, clinical presentation, diagnostic modalities, and available therapeutic strategies. A comprehensive literature search was conducted using PubMed, Embase, Google Scholar and Cochrane databases. Relevant studies were included based on predefined inclusion and exclusion criteria. A narrative synthesis was conducted to summarize and interpret the findings. The prevalence of BRG remains uncertain due to diagnostic challenges. Risk factors include impaired gastrointestinal motility, sphincteric dysfunction (pyloric sphincter and the lower oesophageal sphincter), biliary tract disease, and certain medications. The pathophysiology involves bile acid-induced mucosal injury, inflammation, and impaired gastric defence mechanisms. Clinical manifestations are often nonspecific. Diagnostic modalities primarily include endoscopy and bile acid reflux testing. Management strategies encompass lifestyle modifications, medical therapy, and in severe cases, surgery. BRG is a complex condition with significant clinical implications. Further research is needed to refine diagnostic criteria, elucidate pathophysiological mechanisms, and develop effective therapeutic interventions. Addressing knowledge gaps in epidemiology, risk factors, and long-term outcomes is crucial for improving patient care.
文摘BACKGROUND Fear of childbirth(FoC)is a widespread issue that impacts the health and well-being of mothers and newborns.However,there is inconsistency regarding the prevalence of FoC in the and there is limited research on the prevalence of FoC among Australian pregnant women.AIM To investigate the prevalence of FoC,its risk factors and birth outcomes in Aust-ralian multiparous women.METHODS In this prospective cohort quantitative study,212 multiparous women were re-cruited from antenatal clinics at Westmead Hospital in western Sydney from 2019 to 2022.Pregnant women who attended antenatal visits and met the inclusion criteria signed the consent forms and completed several online questionnaires at baseline.After they gave birth,their birth outcomes were collected from the hospital’s medical record database.The data were analyzed using SPSS software and descriptive statistics,χ^(2)test,independent samples t-test,and multivariable logistic regression analysis.RESULTS Out of 212 participants,24%experienced a high level of FoC and 7%experienced severe FoC.Theχ^(2)test results revealed that a family income of≤$100000,no alcohol intake during pregnancy,pre-existing health problems,previous caesarean section(emergency or planned),and previous neutral/traumatic childbirth experiences were significantly associated with higher levels of FoC(P<0.05).Other risk factors included being moderately to very worried and fearful about the upcoming birth,having severe to extremely severe anxiety throughout pregnancy,and expressing low relationship satisfaction.According to multivariable logistic regression,the odds of a high level of FoC were higher in women with anxiety,a history of traumatic childbirth experience,a history of sexual assault during childhood,pre-existing health problems,and lower relationship satisfaction(P<0.05).CONCLUSION High-severe levels of FoC are experienced by pregnant multiparous women and are affected by several demo-graphic factors.However,due to the small sample size in the present study,further studies with larger sample sizes are required to draw a firm conclusion on the prevalence of severe FoC among multiparous women and its associated risk factors and birth outcomes.
文摘AIM:To describe the demographics,clinical characteristics and treatment outcomes of childhood amblyopia in a tertiary eye center in western India.METHODS:This was a retrospective longitudinal hospital-based study of 1382 children aged≤12y included in the National Institute of OphthalMology AmBlyopia StUdy in Indian Paediatric EyeS(NIMBUS)Study.Data on patient demographics,treatment approach,and best-corrected visual acuity(BCVA)changes were reviewed.RESULTS:The mean age of the study cohort was 4.54±2.46y,with males constituting the majority(55.4%).The cause of amblyopia was refractive error in 73.2%,strabismus in 7.3%,and anisometropia in 6.8%of eyes.The majority of therapies comprised glasses(74.4%),followed by occlusion+glasses(10.3%),occlusion alone(7.3%),and surgery+patching+glasses(5.1%).The mean occlusion time was 2.46±1.14h.After a median follow-up of 10.00(6-85)mo,the mean BCVA significantly improved from 0.85±0.41 to 0.55±0.42 logMAR.Subgroup analysis revealed BCVA gain for all etiologies,including refractive errors(P<0.001),strabismus(P<0.001),cataract(P<0.001),and ptosis(P<0.001).Additionally,eyes with refractive errors showed significantly better BCVA than eyes with cataracts(P<0.001),strabismus(P<0.001)and marginally better BCVA than eyes with ptosis(P<0.05),both at the baseline and final visit.CONCLUSION:Refractive errors are the commonest cause of amblyopia,followed by strabismus and anisometropia.Timely detection,optimal therapy,and periodic follow-up are crucial in bettering visual acuity regardless of the cause.
文摘Background and Objective Hypertension(HT)and atrial fibrillation(AF)are highly prevalent cardiovascular conditions that frequently coexist.Coronary artery disease(CAD)is a major global cause of mortality.The co-occurrence of HT,AF,and CAD presents significant management challenges.This study aims to explore the clinical characteristics and risk factors associated with CAD in patients with HT and persistentAF(HT-AF).Methods In this retrospective cross-sectional study,data were collected from 384 hospitalized HT-AF patients at the People's Liberation Army General Hospital between January 2010 and December 2019.CAD diagnosis was confirmed by coronary angiography or computed tomography angiography.Clinical characteristics and comorbidities were compared between patients with and without CAD.Multivariate logistic regression analyses were performed to identify independent risk factors associated with CAD development.Results The prevalence of CAD among HT-AF patients was 66.41%(255/384).Cardiovascular complications,particularly heart failure(44.7%vs 25.6%,P<0.05),were significantly more prevalent in the CAD group than in the non-CAD group.Only age was identified as an independent risk factor for CAD(adjusted OR:1.047;95%CI:1.022–1.073;P=0.000).Of all HT-AF patients,54.7%had a CHA2DS2-VASc score of≥4,indicating high stroke risk.There was a slightly higher anticoagulant usage rate in the CAD group than those without CAD(8.6%vs 4.7%,P=0.157),and the overall anticoagulant usage remained low.Conclusion There is a high prevalence of CAD among hospitalized HT-AF patients,among whom age is the sole independent risk factor for CAD.Despite a high stroke risk,the utilization of oral anticoagulants is alarmingly low.
文摘Objectives:Depression is one of the most common mental health disorders in adolescence.The aim of this study was to determine the prevalence of depressive symptoms(DS)in adolescents aged 15-18 years in the Autonomous Province of Vojvodina(APV)and to analyze the association of sociodemographic and family factors with DS.Methods:Thesample consisted of 986 students(47.4%females and 52.6%males)fromten government high schools in all seven districts of the APV.The Kutcher Adolescents Depression Scale(KADS)was used as a screening test for DS.Sociodemographic datawere assessed using a self-reported questionnaire.Athree-level binary logistic regressionmodel was conducted to explore the association between sociodemographic and family factors and DS.Results:Symptoms of depression were presented in 27.9%of females(95%CI=23.9%-32.2%)and 14.7%of males(95%CI=11.7%-18.0%)(χ^(2)=25.129,p<0.001).In terms of parents’employment,DS were more prevalent among students whose fathers were unemployed or retired(31.4%,95%CI=20.9%-43.6%)(χ^(2)=4.376,p=0.036).In the multilevel logistic regression model,males had 56%lower odds of having DS compared to females(odds ratio[OR]=0.44,95%CI=0.30-0.65).Students with fathers who completed high school had 46%lower odds of depression compared to those whose fathers had the lowest education level(OR=0.54,95%CI=0.30-0.98),and having an employed mother was associated with 40%lower odds of DS in students compared to thosewhosemotherswere unemployed(OR=0.60,95%CI=0.38-0.95).Conclusions:The study revealed a high prevalence of DS among adolescents.Girls have significantly higher values of prevalence of DS than boys,and adolescents whose fathers are without employment or retired.Gender,the father’s education,and the mother’s employment status are significant predictors of DS.Screening programs and the adoption of targeted prevention programs intended for vulnerable populations are extremely important.

文摘Objective:Children below 14 years of age are highly vulnerable to dengue infection and are at a greater risk of developing severe dengue illness.This study aimed to investigate the trends in the burden of dengue fever among children below 14 years of age in China from 1990 to 2021 and to project the disease burden from 2022 to 2035.Methods:Based on the datasets derived from the Global Burden of Disease Study 2021,the following data were collected from dengue-affected children aged ≤14 years in China from 1990 to 2021:number and rate of incident dengue cases,number of prevalent dengue cases,number of deaths due to dengue,and disability-adjusted life years(DALYs) lost due to dengue.The trends in disease burden were examined based on average annual percent change(AAPC) and annual percent change,and the burdens were proj ected from 2022 to 2035 by using a Bayesian age-period-cohort model.Results:The incidence and prevalence of dengue fever were increased in children aged ≤ 14 years in China from1990 to 2021(AAPC=5.42 % and 5.44 %,respectively,P <0.001),while the mortality and DALYs rates were reduced(AAPC=-8.21 % and-7.55 %,respectively,P <0.001).The burden was comparable between genders,with numerically lower incidence and prevalence in boys than in girls.The lowest incidence and prevalence and the highest mortality and DALYs rates were observed in children aged <5 years.The incidence and prevalence rates were projected to increase from 2022 to 2035;in contrast,the mortality and DALYs rates were projected to decrease during this period.Conclusions:Although the mortality and DALYs rates of dengue fever decreased significantly in children aged0-14 years in China from 1990 to 2021,the incidence and prevalence increased remarkably.Enhanced surveillance and ample health education programs and preventive interventions are recommended for targeting this high-risk population.
文摘Objective:This study aimed to investigate the prevalence and determinants of metabolic syndrome(MetS)among the population in Gannan(Southern Jiangxi),and to develop a nomogram for MetS prediction.Methods:In 2022,a multi-stage stratified random sampling method was used to select permanent residents aged 35 years and above in southern Jiangxi as study participants.MetS was defined according to the International Diabetes Federation(IDF)criteria.Participants'demographics,medical history,blood biochemistry data,and anthropometric variables were collected to screen for significant variables for the prediction model of MetS.Multivariable logistic regression was employed to explore the factors associated with MetS.Subsequently,the data were divided into a training set and a validation set,and a nomogram was developed to create the predictive model for MetS.The training set was utilized for nomogram model construction and preliminary validation,while the validation set was used for internal validation.The performance of the nomogram was assessed based on receiver operating characteristic curve(ROC),calibration curves,and decision curve analysis(DCA).Results:A total of 1581 participants were enrolled in the study,revealing a prevalence of MetS of 27.39%(95%CI:25.19%-29.59%).The age-standardized prevalence was calculated to be 27.81%.Nine variables were identified as influencing factors for MetS:age,residence,occupation,history of hyperlipidemia,history of hyperuricemia,hip circumference,glycated hemoglobin A1c(HbA1c),resting heart rate(RHR),and body mass index(BMI).The participants were randomly divided into a training set(n=1107,70%)and a validation set(n=474,30%).The nomogram was validated through preliminary validation area under curve(AUC:0.844)and internal validation(AUC:0.825).Calibration plots demonstrated good agreement in the training sets.Conclusion:The prevalence of MetS is notably high in Ganzhou,Jiangxi.The nomogram,which is based on age,residence,occupation,history of hyperlipidemia,history of hyperuricemia,hip circumference,HbA1c,RHR and BMI variables,exhibits strong predictive efficacy and can be utilized to assess the risk of MetS in middle-aged and elderly populations.
文摘The exact worldwide prevalence of gastroesophageal reflux disease(GERD)re-mains uncertain,despite its recognition as a common condition.This conundrum arises primarily from the lack of a standardized definition for GERD.The gold standard diagnostic tests for GERD,such as pH impedance testing and endo-scopy,are cumbersome and impractical for assessing community prevalence.Consequently,most epidemiological studies rely on symptom-based screening tools.GERD symptoms can be both esophageal and extraesophageal,varying widely among individuals.This variability has led to multiple symptom-based definitions of GERD,with no consensus,resulting in prevalence estimates ranging from 5%to 25%worldwide.Most systematic reviews define GERD as experi-encing heartburn and/or regurgitation at least once weekly,yielding a calculated prevalence of 13.98%.In 2017,the global age-standardized prevalence of GERD was estimated at 8819 per 100000 people(95%confidence interval:7781-9863),a figure that has remained stable from 1990 to 2017.Prevalence increases with age,leading to more years lived with disability.GERD significantly impairs quality of life and can lead to multiple complications.Additionally,it imposes a severe economic burden,with the United States alone estimated to spend around 10 billion dollars annually on diagnosis and treatment.In summary,GERD preva-lence varies greatly by region and even within different areas of the same province.Determining the exact prevalence is challenging due to inconsistent diagnostic criteria.However,it is well-documented that GERD poses a significant global burden,affecting the quality of life of individuals and creating a substantial healthcare cost.
